- No. 899,958. Specification of To all whom it may concern:

Be it known that I, WILLIAM H. DANIELS, a citizen of the United States,residing at' Chicago, in the county of Cook and State of Illinois, haveinvented new and useful Improvements in Building- Blocks or Bricks, ofwhich the following is a specification.

My invention has relation to a brick or building block for use inbuilding chimneys or other,structures,'and it consists in theconstruction and arran ement of parts as will be hereinafter describedand particularly pointed out in the claims.

' In the accompanying drawings, Figure 1' is a sectional view of theupper portion of 'a chimne constructedof my improved bricks or blocks.Fig. 2 is a top plan View of one course thereof showing the interlockingbonding joints between the meeting ends of the several bricks or blocksin such course. Fig. 3 is a detail perspective viewof one of my 4 .imroved blocks.

n accordance with my invention, I provide a brick or block A which maybe made, of an suitable material, and may be of any suita 1e size. Theblock is. constructed substantially of arectangular parallelopi edonshape and having on opposite ends it ereof vgrt cal projections .3 ofthe same thickness a said block but of less width than the same,

I ifihereby a rabbeted end 4 is formed, said" ock being providedwith apair of endless grooves -1 and 1', each of said grooves eX- I tending ina vertical direction over said end portion and said rabbeted end andparallel to the edges of said block on the upper and lower faces of thesame, thetwo transverse faces of said ends being each provided with ,oneof said grooves.

111 constructing a.chimney, the above described block is used inconjunction with corner blocks B, as shown in Fig. 3. These blocksdiffer from the blocks A in that the end 6 is a plane surface instead ofa rabbeted surface and thefpr'ojection 5,'similar to the projection 3,is rmed on one side adjacent the end 6. These blocks arealso providedLetters Patent.

claimand desire to secure by Letters Patent 1s stantially of arectangular parallelopipedon and having the vertical ortions which are.of other blocks formed with vertica projecof less width than the same,said block'being provided with a pair of endless grooves, each of saidgrooves eiitending in a vertical direc-v tion over said verticalportions and parallel to the edges of the block on its upper and lowerfaces, the two transverse faces of said vertical portions being eachprovided'with one of said grooves.

stantially of a .rectangular parallelopipedon and having onc end provide'blockbut of less width than the same, whereby a: rabbeted end isformed, said block have ing the end portion of one side at theopporojection of the same thickness as the block block being providedwitha pair of endless said rabbeted end and parallel to the edges oftlie block on its upper and lower faces, the two transverse faces ofsaid end portion and said rabbeted end being each provided with one ofsaid grooves. p In testimony whereof, I affix my signature in presenceof two Witnesses.
